[0031] Preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely used to explain the technical principles of the present utility model, and are not intended to limit the protection scope of the present utility model.

[0032] It should be noted that in the description of the present utility model, terms indicating direction or positional relationship such as "inner", "outer", "upper", "lower", "top", "bottom" are based on the direction or positional relationship shown in the accompanying drawings, which is only for the convenience of description, rather than indicating or implying that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present utility model.

[0033] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "arrange", "mount", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meaning of the above terms in the present utility model can be understood according to specific circumstances.

[0034] Based on the problem pointed out in the background art that the ice making device of the existing refrigeration equipment requires users to add water manually, which leads to the cumbersome ice making process and difficult guarantee of water quality, the present utility model provides a household electrical appliance system for a washing machine. By connecting the pure water outlet of the water purification device with the ice making device of the washing machine through an ice making pipeline, arranging an ice making valve on the ice making pipeline, and realizing the linkage control of the ice making valve and the water purification device through a controller and a sensor, the water purification device can automatically operate when the ice making device is short of water, so as to introduce the produced pure water into the ice making device, which makes the ice making process simpler and more convenient, and ensures the cleanliness and hygiene of water for ice making at the same time.

[0035] Specifically, as Figure 1 shown, the household electrical appliance system of the present utility model comprises a refrigeration device, a water purification device, an ice making pipeline 1 and an ice making valve 11.

[0036] Wherein, the refrigeration device can be various refrigerators or freezers with ice making function. In the present case, a commonly used household refrigerator is taken as an example for description. An ice making device is arranged in the refrigerator, and the ice making device comprises a water storage container for storing water for ice making. The refrigerator can freeze water into ice cubes of various shapes by using its internal refrigeration system. The refrigerator is also provided with a water replenishing port that connects the water storage container with the outside, so as to facilitate water replenishing into the water storage container.

[0037] The water purification device can be various water purifiers, and comprises a raw water inlet 21 and a pure water outlet 22. The raw water inlet 21 communicates with an external water source (such as a water tap), and can introduce tap water into the water purifier. After being purified and filtered in the water purifier, the tap water flows out from the pure water outlet 22 to obtain pure water.

[0038] Ice-making tubing 1 connects the water purifier and the refrigerator. Its inlet is connected to the pure water outlet 22 of the water purifier, and its outlet is connected to the ice-making unit of the refrigerator, so as to directly introduce pure water into the water storage container of the ice-making unit. In practical applications, the length of ice-making tubing 1 can be flexibly set, and the material preferably used is a flexible hose to adapt to the placement of the water purifier and the refrigerator.

[0039] An ice-making valve 11 is installed on the ice-making pipeline 1 and can control the opening and closing of the ice-making pipeline 1. This allows the ice-making pipeline 1 to be connected when the refrigeration unit is short of water, enabling pure water from the water purification equipment to enter the ice-making unit along the ice-making pipeline 1. In practical applications, the ice-making valve 11 can be a mechanical valve, controlled manually. This application preferably uses a solenoid valve, which can be controlled by the refrigerator's control panel, allowing the user to control the opening and closing of the ice-making valve 11 via the control panel. Alternatively, it can be controlled by a water level sensor within the ice-making unit, opening when the water level for ice making is too low and closing when the water level rises.

[0040] Preferably, the home appliance system also includes a sensor 3, which is electrically connected to the controller of the water purification equipment (not shown in the figure) and signal connected to the ice-making valve 11. The sensor 3 can sense the opening and closing signals of the ice-making valve 11, and the controller can control the start and stop of the water purification equipment according to the opening and closing signals.

[0041] For example, the controller, sensor 3, refrigerator, and water purifier are all connected wirelessly or wired to achieve data interaction. Preferably, this application uses wireless communication technologies such as Wi-Fi or Bluetooth for data interaction. When the ice-making valve 11 is opened due to a lack of water in the ice-making device, the sensor 3 will sense the opening signal of the ice-making valve 11 and transmit the opening signal to the controller. After receiving the opening signal of the ice-making valve 11, the controller will control the water purifier to run and start making water to continuously produce pure water and ensure the water supply of the ice-making device.

[0042] Regarding the type and structure of water purifiers, in practical applications, the types and structural distribution of their internal filters can be flexibly set, such as at least one of RO filter, PP cotton filter, activated carbon filter, quartz sand filter, and softening filter.

[0043] Preferably, such as Figure 1 As shown, the water purification equipment of this utility model includes an inlet valve 4, a booster pump 5, and an RO filter 6. The inlet end of the inlet valve 4 is connected to the raw water outlet 21, the outlet end of the inlet valve 4 is connected to the inlet end of the booster pump 5, the outlet end of the booster pump 5 is connected to the inlet end of the RO filter 6, the outlet end of the RO filter 6 is connected to the pure water outlet 22, and the wastewater end of the RO filter 6 is connected to the outside to discharge the concentrated wastewater generated to the outside. The controller is electrically connected to the inlet valve 4 and the booster pump 5, and the start and stop of the water purifier are controlled by controlling the inlet valve 4 and the booster pump 5.

[0044] The inlet valve 4 is used to control the flow of tap water. After the booster pump 5 is turned on, it can pressurize the water flow to force the water flow through the RO filter 6. The RO filter 6 can filter out heavy metals (such as lead, mercury, cadmium), bacteria, viruses, organic matter and inorganic salts in tap water, so that the purified water is close to the pure water standard and improves the water quality. The controller can be electrically connected to the booster pump 5 and the inlet valve 4 to start the water production process as needed, so that it can be turned on as needed.

[0045] More preferably, such as Figure 1 As shown, the water purification equipment of this utility model also includes a pre-filter 71, which is set between the raw water inlet 21 and the inlet valve 4. It is preferably equipped with a PP cotton filter element or various filter media inside to perform coarse filtration on the tap water, filter out large particulate impurities in the tap water, and prevent impurities from damaging the RO filter 6 and affecting its lifespan.

[0046] The water purification equipment may also include a post-filter 72, which is located between the outlet of the RO filter 6 and the pure water outlet 22. It preferably contains an activated carbon filter element, which can adsorb residual chlorine, residual chemicals and odors in the purified water to improve water quality and taste.

[0047] In this application, in order to save internal space in the water purifier, different filters can be integrated together for installation.

[0048] Preferably, such as Figure 1 As shown, this application integrates the pre-filter 71 and the post-filter 72 together. In addition to saving space, it also takes advantage of the fact that the replacement cycles of the pre-filter 71 and the post-filter 72 are close, making it easy to disassemble and replace them simultaneously.

[0049] It should be noted that, regarding sensor 3, in practical applications, those skilled in the art can flexibly set it to various types, such as pressure sensor, flow sensor, or opening sensor, etc.

[0050] Preferably, the sensor 3 of this invention is a high-pressure switch, which is installed on the ice-making pipeline 1 and senses the opening and closing signal of the ice-making valve 11 by sensing the water pressure change signal in the ice-making pipeline 1.

[0051] High-voltage switches are simple in principle, easy to install, and have high sensing sensitivity. They ensure the linkage control of water purification equipment and refrigeration equipment while also helping to save costs.

[0052] Specifically, when the ice-making valve 11 is normally closed, the water inlet valve 4 and the booster pump 5 are closed, and the ice-making pipeline 1 is filled with pure water. At this time, the water pressure sensed by the high-pressure switch is relatively high, usually between 2.0 and 2.4 MPa. When the ice-making device needs to replenish water, the ice-making valve 11 is opened, and the pure water in the ice-making pipeline 1 flows to the ice-making device, causing the water pressure to drop. When the water pressure is lower than the preset water pressure, usually 2.0 MPa, the high-pressure switch will transmit the signal of the reduced water pressure to the controller, so that the controller controls the operation of the water inlet valve 4 and the booster pump 5 to start the water making process. When the water volume in the ice-making device reaches the preset water volume, the ice-making valve 11 is closed, and the controller controls the water inlet valve 4 and the booster pump 5 to close, ending the water making process.

[0053] like Figure 1 As shown, in a preferred embodiment of this application, the home appliance system further includes a pure water return pipe 81. The inlet end of the pure water return pipe 81 is connected to the outlet end of the RO filter 6, and the outlet end of the pure water return pipe 81 is connected to the inlet end of the inlet valve 4. By introducing pure water into the inlet end of the inlet valve 4 and mixing it with tap water, the water quality before entering the RO filter 6 can be improved, the TDS value can be reduced, thereby reducing the pressure on the RO filter 6 and helping to extend the service life of the RO filter 6.

[0054] In another preferred embodiment of this application, the home appliance system further includes a wastewater return pipe 82, with its inlet end connected to the wastewater end and its outlet end connected to the inlet end of the inlet valve 4. By introducing wastewater into the inlet end of the inlet valve 4 and mixing it with tap water, the wastewater can be filtered a second time to increase the yield of pure water and reduce water waste.

[0055] In addition, the household appliance system of this utility model also includes a direct drinking water pipe 9, the inlet of which is connected to the pure water outlet 22, and the outlet of which is connected to the outside. This allows the pure water produced by the water purifier to supply not only the ice-making device but also the user's drinking water, meeting the user's diverse water needs.

[0056] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
